ASSESSING THE NON-FINANCIAL INVESTMENT PROFITABILITY WITH VARIABLE DISCOUNT RATE

In the work, the subject of the discount rate assessment is presented. The discount rate is usually considered as constant in the whole investment period, which seems to be the main problem. The constant discount rate does not take into account the actual money loses value in time. Moreover, the discount rate elements can change in time, and it should be remembered that many factors, which could also change, influence the value of those elements. The research confirms that the assumption of using the constant discount rate is erroneous. In the work one can find i.a. the methods of own capital assessment or the proposal of different techniques of risk premium valuation.
